【摘要】 目的:观察单个上前牙或下颌2个以内前牙缺失采用IPS Empress 2或IPS e.max热压铸造全瓷粘接桥的临床修复效果。方法:22位患者,共制作26件前牙热压铸造全瓷粘接桥,包括16例单翼全瓷粘接桥和10例双翼全瓷粘接桥,修复后3个月、6个月、1年,2年和3年观察修复体的完整性,基牙的继发龋,边缘着色及修复体的颜色匹配。结果:1例双翼全瓷粘接桥修复后3个月脱落;1例双翼全瓷粘接桥6个月后一侧连接体折断,均改为单翼全瓷粘接桥后继续使用;1例双翼全瓷粘接桥修复后2年脱落,修复体完整,重新粘接后继续使用,没有继发龋和边缘着色,颜色与邻牙相协调。整体修复成功率为88.5%。结论:对于2个以内前牙缺失的患者,采用IPS热压铸造全瓷粘接桥可以取得较好的临床修复效果。更多还原

【Abstract】 Objective:To clinic observation of IPS Empress2 and IPS e.max all ceramic resin bonded fixed partial dentures used in one anterior teeth lost in upper jaw or less than two anterior tooth lost in lower jaw.Methods: 22 patients,26 restorations had been made,which included 16 single-retainer all ceramic resin bonded fixed partial dentures and 10 two-retainers all ceramic resin bonded fixed partial dentures.Secondary caries of the abutments,shade in the margin of the retainers and the integrity of the restorations had been observed at 3 months,6 months,1 year,2 years and 3 years after all ceramic resin bonded fixed partial dentures having been bonded.Results: In the 3 years of clinic observation of the anterior all ceramic resin bonded fixed partial dentures,1 two-retainers restoration lost bond after it had been made for 3 months,a retainer of one two-retainers restoration was broken after 6 months,but they are still used after modified as one-retainer all ceramic resin bonded fixed partial dentures,1 two-retai-ners restoration lost bond two year later,It was integrity and re-bonded again that was still stable.No secondary carries and no shade in margin of the retainers had been found.Their color matches with the nature teeth excellently.The success rate was 88.5%.Conclusion: IPS Empress 2 and IPS e.max all ceramic resin bonded fixed partial dentures should be a good selection in one or two teeth lose in anterior jaws.更多还原
